IMPROVEMENT IN MACHINES FOR FINISHING DRAIN-TILES.

Specification forming part of Letters Patent No. 126,929, dated May 21,1872.

Specification describing anew and Improved Drain-Tile Jointer, inventedby ANDREW L. BROWN, of London, in the county of Madison and State ofOhio.

Figure 1, Sheet 1, is a side view of my improved machine. Fig. 2, Sheet2, is a detail sectional view of the same taken through the line a: 00,Fig. 1. Fig. 3, Sheet 2, is a detail longitudinal section of a couple oftiles illustratin g the joint.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish an improved machine forbeveling one end and recessing the other end of lengths of draintiles toform gt joint, and which shall be simple in construction, convenient inuse, and effective in operation; and it consists in the construction andcombination of various parts of the machine, as hereinafter more fullydescribed.

A represents the frame-work of the machine. B is the driving-shaft,which is hung in bearings attached to the lower part of the frame A, andto one of its ends is attached a pulley to receive the belt by whichmotion is communicated to said shaft. To the shaft B, near each end, isattached apulley, D. E are bands, which pass around the large pulley l)and around the small pulleys F, which are placed upon the short shaftsG, with which they are connected by a tongue and groove, a slot and'pin, or other device which will allow the shafts G to be movedlongitudinally through the pulleys F while being carried around by andwith said pulleys .in their revolution. The shafts G revolve in bearingsin the brackets H attached to the upper part ofthe frame A, and againstwhich brackets the hubs or sides of the pulleys F rest to keep them inplace. To the outer ends of the hubs of the pulleys D, or to the shaft Bat the outer sides of said pulleys, are attached, or upon them areformed, flanges'or wheels I, upon the edge of which rests the forkedlower ends of the levers J, the said flanges or wheels being made withan outwardly-projecting offset or cam, as shown in Fig. 1, to give anoutwardmovement to the lower ends of the said levers J at the propertime. The levers J are pivoted at their middle part to the frame A, andtheir upper ends are forked to ride in a groove around the outer ends ofthe short shafts G, so that the said shafts may be moved out and inautomatically by the movement of the levers J. K is an arm, which passesthrough the inner end of one of the shafts G, at right angles to saidshaft, and is adjustably secured in place by a set-screw, wedge-key, orother convenient fastening. The upper end of the pin K is bent inward atright angles, as shown in Fig. 1; L

is a wire, one end of which is attached to the end of the arm or rod K,and its other end is is attached to the body of said pin in such aposition as to give the desired bevel to the outer edge-of one end of alength of draintile, as indicated in Fig. 1. To the other shaft Gr, nearits inner end, is attached a straight arm, M, to which is attached oneend of a wire, N, the other end of which is attached to a short arm, 0,attached to the inner end of the shaft ,G. The wire N is arranged atsuch an inclination as will give the desired bevel to the inner edge ofthe other end of the tile-lengths or sections. The wiresL N, whenadjusted, should be exactly parallel with each other, so that theadjacent ends of the lengths or sections may fit each other accuratelyand form a close joint. The tile, while being operated upon, issupported and held by-a holder or carrier, P, which receives the tilefrom the table Q attached to one side of the top of the frame A, anddelivers it upon the table R attached to the other side of the frame A.The table Q should be a little higher and the table R a little lowerthan the carrier 1?, so that the tile can be conveniently rolled fromthe table Q into the carrier P, and from the said carrier P to the saidtable R. The carrier P is attached to a bed-plate, S, the ends of which,or

lugs formed upon said ends, are pivoted to a rod, T, the ends of whichare attached to the upper ends of the side bars of a frame, U. To theside bars of the frame U are attached keepers V to receive the bars W,and which are adj ustably secured to said bars W by setscrews X, asshown in Fig. 1. The bars W are rigidly attached to the frame A, andserve as supports and ways for the frame U. This construction allows thecarrier to be turned to the table Q to receive the tile, and to thetable R to discharge it. The table Q is made with a flange, Y, at oneend, to serve as a guide in adjusting the tiles. The carrier 1? shouldbe detachable, so that it may be detached from the carrier S andreplaced with one of a differentsize to correspond with the size of thetiles to be operated upon, the frame U being adjusted upon the bars Waccordingly. To the middle part of the bed-plate S, near one side, ispivoted the upper end of the connectingrod Z, which is made in twoparts, sliding upon each other, and secured by a set-screw, so that itmay be conveniently adjusted in length, according to the adjustment ofthe frame U. To the lower end of the adjustable connectingrod Z isattached a pin, A, which passes through a guide slot or groove, B, in agrooved wheel, 0, attached to the shaft B, so that the carrier P may bemoved automatically to the table Q to receive the tile, may be movedbeneath the shafts G and held while its ends are being operated upon,moved to the table R to discharge the tile, and again moved back to thetable Q, to receive another tile. 1) is a bar, one end of which isattached to the lower end of the connecting-rod Z or to the pin A, andits other end is attached to the frame A. The bar D is designed toassist the slotted or grooved wheel B 0 in controlling the movements ofthe carrier .P. One of the belts E may be crossed, and t he otherstraight, to revolve'the cutters in opposi tedirections, so that theymay tend to hold the tile while being operated upon securely in place.

Having thus described my invention, I claim as new and desire to secureby Letters Patent-- 1. The combination of the pulleys D, bands E,pulleys 1?, shafts G, cam or guide wheels I, and pivoted levers J withthe driving-shaft B and cutters K L M N O, substantially as herein shownand described, and for the purpose set forth.

2. The pivoted carrier P, in combination with the receiving anddischarging tables Q R and cutters K L M N O, substantially as hereinshown and described, and for the purpose set forth.

3. The combination of the adjustable frame U, stationary supporting-barsW, adjustable connecting-rod Z, pin A, grooved or slotted cam-wheel B G,and arm D, with the driving-shaft B and pivoted carrier P, substantiallyas herein shown and described, and for the purpose set forth.
